Try one of these fun experiments to learn about your composting worms’ food preferences.

Half a cantaloupe in the worm bin experiment

• Don’t feed your worms for a week or so, so that they are good and hungry.
• Cut a cantaloupe in half
• Place it flesh side down on top of your worm bin, close the lid
• Leave it for 3 days
• Come back and check, your cantaloupe should be full of red wiggler worms enjoying the sweet, soft flesh
• Put the cantaloupe back and leave it for a week or so. The composting worms will devour all the melon flesh and leave a paper thin rind.

Experiment: What do your worms like to eat more?

• Don’t feed your worms for a week or so, so that they are good and hungry.
• Choose two different types of worm food.
• Bury the different types of worm food in opposing corners of your worm composting bin.
• Leave them alone for 3 or 4 days and then come back and check on which they have eaten first.
• Continue this experiment over and over to find their ultimate favorite food. Maybe get nerdy and make a ‘march madness’ style bracket. “Worm Food Madness!”

Have fun with these red wiggler worm’s favorite food experiments!
